The Electro-Harmonix Pitch Fork is a polyphonic pitch shifter that can be used with an array of instruments, including guitars and keyboards. It can harmonize within a range of +/- three octaves, adhere to fixed intervals, and be controlled remotely via foot pedal or CV.
Users can select transposition intervals with the unit’s 11-position switch, which moves from half-step transposition all the way to three octaves. There’s also a three-position toggle switch for configuring the harmonization in either octave-up, octave-down, or simultaneous operation.
When operating in Dual mode, users can choose how their note is harmonized in accordance with two others (this process is primarily based around 3rds and 5ths). All this plus a blend knob means users have everything they need to dial in the perfect effect.

Electro Harmonix Pitch Fork pedal
The Pitch Fork transposes an instrument’s pitch over a +/- three octave range and features three modes which allow the pitch to be transposed up, down or both, simultaneously. The pitch shift amount can be set to a fixed interval or continuously varied by an expression pedal or control voltage.
The controls are straightforward and intuitive. An 11-position Shift switch selects the maximum transposition interval ranging from D (Detune), a shift of 17 cents, through Minor 2nd, Major 2nd, Major 3rd, Perfect 4th, Perfect 5th, Major 6th, Minor 7th, 1 Octave, 2 Octaves and 3 Octaves.
